GIN OR LINTEB SAW.

Specification of Letters Patent.

A ncanonmea June 22, 1919. Serial No. 305,997.

gins or linters comprising disks having den tations or teeth at theperiphery mounted in juxtaposed relation upon a shaft to constitute asaw cylinder. To obviate the neces sity of removing the disks from theshaft to sharpen the teeth or to substitute a new saw for a saw theteeth of which have been broken or worn the dentated or toothed por--tion of the saw is made separate from the disk, the latter serving as acarrier for said toothed portion, and said toothed portion and the diskare arranged to releasably secure the two together for which pur osevaowever, in all such securing means portions protrude or project fromthe side of the disk forming obstructions. In the use of the saws aportionengages in or extends through spaces in what is known as a ribbreast of the in orlinter andupon which the cotton to ginned issupported, the saws operating to pull the fiber or lint from the seedsthrough such spaces. These spaces are relatively small to prevent theseed from failing therethrough during the ginning operation. The disksor carriers are made of relatively thin and springy sheet material, suchas steel, with the rwult that often they are warped "or distorted and inthe use of securingmeans whereportions protrude from the side of thedisk such protuberanoes strike of the openingsin the rib breastrupturing and breaking off such securing means. i p

Itis the object of the present invention to provide a saw in which i thedentated or toothed portion of the saw is releasable from the disk orits carrier; and to provide an improved method of and means forreleasably securing the toothed portion to its carrier which is noveland cheap inconstruction, and which securin means forms no obstructionprotruding romlthe side of the disk but presents a smooth and unbrokensurface.

In the drawing accompanying and formingapart of th s specificationhigure 1 is a plan view of a portion of a saw cylinder with anembodiment of my improved saw applle'd thereto and showing the relationof the saw to the rib breast of a in or linter.

In Figs. land 2 of the drawing I have shown an embodiment of myinvention in connectlon with a portion of the rib breast of a cotton ginor linter, comprising a series of ribs 7 mounted in juxtaposed relationat opposite ends upon supports 8, 9, as by screws passing throughopenings in the ribs and threaded into the supports, and the ribs arearranged to provide relatively narrow spaces 10 between the ribs throughwhich a portion of the peripheral and toothed portion of the saws areadapted to extend toengage the material supported upon the rib breast tobe ginned or cotton seed to be linted, the spaces 10 being of such widthas to prevent the seed from falling therethe difi'erent views ofPatented Jan. 18, 1921.

through. The saws are mounted upon a shaft 12 torotatetherewith injuxtaposed relation and spaced apart by spacing blocks or collars 13interposed between the saws.

My improved saw comprises a circular carrier and anannulus of less widththan from the axis to the circumference of the saw, preferablyconsisting of segmental sections formed with dentations orteeth at theexternal edge, and either one of which is arranged with a turcatedportion for the engagement of the other, and the legs ofthe furcatedportion being yieldable and by their inherenttension to lie contiguousto each other, although adapted to be sprung laterally.

The construction ofsaw shown in Fig. 5 and which may be the preferredform, comprises a pair of circular members or disks 14, 14. of" springymaterial fixed together ata point within the periphery, asby spotweldthejuncture portion rounded.

ing indicated in a general'way at 15. By so connecting the disks anintegral disk memher is provided the peripheral portions oi I Which arefree andforming a bifurcated pcripheral portion. The free or bifurcatedportion of the dlSKS 1s arranged with concentric. corrugations or beads16 with the Within the toothed edge to extend to the edge opposite totheteeth. The sections of this annulus are adapted to between the legs ofthe bifurcation the periphery of the disks or carrier, and thecorruga'ruims of the sections are complementary to the corrugations insaid bli'urcated portion.

Ff) limitthe movement the sections of the an nulus into the bifurcationone of the disks has an annular recess Within the corrugated portion asshown at 20 to form a seat for the engagement of the internal edge ofthe annulus sections, this recess being located so that only the toothedzone of the blade or annulus will project beyond the periphery of thedisks. 14'. The cross sectional shape or form of the corrugations of thedisks and blade is such that the inclination or". one portion of thecorrugations will extend it an acute angle to the sides of the disks anoblade as shown at 21 and the 0 DOOSitG nor- Y tion extends at an obtuseangle to the E 1 ice of the disks and-blade, as shown at 22, with Bythis arrangement the blades may be readily forced into the bifurcation,the uncorrugated portions ofthe the bifurcation readily riding over theinclined portions 21 of the corrugations of the blade sections, and whenthe corrugations of the blade sections engage in the corrugations of thebifurcation the inclined portions .22 of the corrugations servingto-lock the blade sections in position,

although they may be readily released by a radial pullon the bladesections. By this arrangement of securing the blade sections to thecarrier although the corrugations project laterally from'the carrier,such projections present a continuous and unbroken surface Withoutforming any obstructions to strike against the ribs ofthe rib breast ofthe cottongin or linter should the carrier be Warped or distorted withthe consequent rupturing or breaking of the securing means and therebythe releasingof the blade sec tions from the carrier.

In the modification shown in Fig. 6 the construction is substantiallythe same as described with the exception that instead of utilizing apair of disks and securing" them together in such a manner as to providea bifurcated portion at the periphery on y one disk is utilized arrangedwith the an nLlar corri .tions ber is fastened to the disk adjacent itsinner edge. preferably iy spot welding as shown at 26, with the externaledge oncentric with the periph oi the disk and the inherent tension oi"the material of said member being such. that it will nornmllv liocontiguous to the disk. The annular member 25 is arranged withcorrugations complemental to the oorrugutimis ll; of the disk and theannular reressod portion 20 to form a seat for the interred edg: oi thesaw blade sections 19.
